plugin works only once

Once installed the plugin works as expected (loading my `.env` vars in `process.env` being used in webpack and all), but after a node reload or any changes, it suddenly stops to populate `process.env`.

I can make it to "work" again either by changing in `.babelrc` the `path` option value (which I should not need, my `.env` is at the root of my repository) or by running a new `yarn install --dev babel-plugin-inline-dotenv` to clean it up, which makes me wondered if there's some sort of cache messing up here ?
Once it stops working for a specific `.env` path, it won't use it again no matter what until reinstalled.
